8 months into ownership, I get my first check engine light. Had O'rielly's pull codes P0171 & P0174. After a little research on the forum, I popped the hood in search of a vacuum leak. Didn't take long to identify the upper IMT as the culprit. Ordered o-rings from Jaguar of Troy Tuesday, they arrived Friday, and after 20 minutes under the hood, the job is done. As stated by others, the bottom o-ring was easily slipped over the module from the outside; no need to remove the intake. CEL is off, we'll see what the next couple of days bring.

 

Nicely done! Hope that you just set the stage for more trouble free motoring through 2013! And if not, feel safe in knowing that chances are any problems can be diagnosed and fixed here on this forum.

 

rantsc, I realized that after fixing my p0171 and p0174 codes I got about 3 mpg better and I was just wondering if you got the same results? If so, this could be useful information to help out others who are experiencing very low mpg

 

Tuned in on that note, I was averaging 14mpg on the old engine with the random misfire codes, hopefully there is a big difference with the newer motor going in,
